I had studiously ignored the case handling discussion of a few weeks ago, but now the problem has hit home. Since the installation of 1.5k, LISTSERV doesn't always convert the address it gets from node TAURUS, a local UNIX machine, to uppercase: 19 Jul 1987 12:28:04 Received file (3225) from LEONID@TAURUS * You are not authorized to mail to list ILAN-L 19 Jul 1987 12:28:08 Sent information mail to LEONID@TAURUS 19 Jul 1987 12:28:08 RSCS message: LOCATION taurus IS NOT DEFINED Leonid IS authorized to mail to this list (DS). 19 Jul 1987 22:33:41 Received file (0472) from HART@TAURUS 19 Jul 1987 22:33:45 From hart@taurus: INFO PR 19 Jul 1987 22:33:46 Sent file "LISTPRES MEMO A1" to hart@taurus RDR FILE 9532 TRANSFERRED FROM RSCS Source node not found in table. 19 Jul 1987 22:33:48 From hart@taurus: REG hart 19 Jul 1987 22:33:48 To HART@TAURUS: * You must specify your full name, for e ample: 19 Jul 1987 22:33:48 To HART@TAURUS: * REGISTER John A.

I just noticed today that the same problem has occurred with another UNIX machine. Am I the only one with this problem? Is this what I get for allowing remote installation? David
